Live Earthquake Mashup

The Live Earthquake Mashup enables you to view live earthquake data from several sources. The events are shown simultaneously on a timeline (using the Timeline widget from project Simile) and a map (provided by Google Maps). You may switch between these data sources:

USGS 2.5+, USGS 5+

The United States Geological Survey offers several data feeds, these two show events of the last seven days, either of magnitude 2.5 and stronger, or magnitude 5.0 and stronger, respectively. The data covers big earthquakes worldwide, but emphasises US territory (mainly Alaska, Puerto Rico and California) for weaker events.

EMSC

The European-Mediterranean Seismological Centre distributes data on earthquakes of the last 24 hours. Again, big events from around the world are shown, with smaller events from across Europe, especially the Mediterranean Sea (Greece, Aegean Sea and Turkey).

GFZ

The GeoForschungsZentrum Potsdam provides data for earthquakes of the last 24 to 48 hours, mainly strong ones from all over the world.

The selected data feed is reloaded every five minutes, the countdown shows the remaining time.

You may move the timeline and the map as you like. If you click on a marker in either of the two, an info window will open with detailed information on the event, and a link to more information on the website of the feed provider.

If the feed is reloaded after five minutes, the timeline and the map are moved, so that the most recent earthquake is shown in the center of the screen. If you uncheck the "follow" box, the timeline and the map stay where they are. This allows you, for example, to compare the data provided by the different institutions for a certain area.

A Note to Users of Microsoft's Internet Explorer

As IE user, you are probably aware of the fact that your browser disregards many standards. I have taken some measures to tweak the mashup, so it is usable with IE. For best performance, please consider switching to a more standards compliant browser, like Firefox, Opera, Safari, Konqueror or Chrome , to name a few. To give you an idea what you are missing, compare these two screenshots:

Firefox 3.0.1 (with transparent icons, indicating the age of the earthquake):
